    The TT Diamond seemed like the clear favorite and I guess I can turn it up some if I want, so I went that route.... One more part down.

    I've had so many Ruger Rifles and Handguns over the years. In fact I'm about to purchase a Ruger Super Blackhawk from a friend. In my honest opinion Ruger nearly always gives a lot of bang for the buck.

    Mounted the TT Diamond up to my Origin, and after reading about having triggers timed for custom actions, I find myself wondering "how do you know if your trigger is properly timed or not?". Is there some kind of indicator in the feel of the bolt closing?

    As an aside, I'm already glad I got the TT, it's easily the best trigger I've ever felt, much less owned, really crisp and downright amazing at the lower weights.

    All I know about it at the link. Basically how much sear contact/interaction. Get the trigger too low, and there won't be enough contact, and can cause a slam fire when you "slam" the bolt home running it fast. Maybe someone can tell us more.

    https://impactprecisionshooting.com/products/trigger-hanger?_pos=1&_sid=b9e48f130&_ss=r

    When I bought my 2nd Impact action it was an action only, and I ordered a hanger set because I did not know they would ship it with a trigger hanger. I went with the one that came with the action.

    For anyone in a similar situation in the future, I just wanted to add that I emailed Zermatt with this question and got the following response:

    Gtscotty,

    We have the Origin's setup to run the TriggerTech triggers without any timing issues. It should be spot on when you have it all together.

    Thank you,

    Also on case anyone is looking for barrels, PVA is having a labor day sale the coupon code "TaxationIsTheft1787" is good for 17.87% off. I'm planning on ordering a 23" Rock Creek shouldered prefit in 6mm GT, I guess in the M24 profile (seems to be their standard profile?). I know 26"-28" are preferred lengths for this kind of thing, but I will be using a suppressor 100% of the time and don't really want my total barrel length to be too much over the ~30" mark.

    PVA and Rock Creek are both 4 letter words in my book. Eccentric brakes, excessive bevel on chambers leaving insufficient case support which blows out a magazine and extractor, PVA is on my no-go list. Inexplicable 1/2 barrel life with customer service totalling “I don’t know what to tell you, I get 3000-4000 rounds from 6 creed before losing speed” when contacted about a barrel which dumped 120fps by 800 rounds and then had dropped almost 400fps by 1200 rounds put Rock Creek right there in the list beside PVA.

    Interesting to me why a barrel would dump speed after a low round count.

    More “interesting” to me was that contacting the barrel maker about what was a defective barrel yielded “that’s weird, that doesn’t usually happen,” which was NOT followed by any action by Rock Creek to figure out why it was happening. At that point, I was a couple dozen barrels deep into 243win and AI, a handful of Dasher tubes, and one 6 creed factory barrel down - not to mention networked with hundreds of other competitive 6 creed shooters - so I had a feel for how long 6 creed barrels should last. No support for the barrel beyond saying the fact mine was burning out twice as fast as it should have and THEN telling me, and asserting twice, that he gets 3000-4000 rounds on 6 creed before losing accuracy or speed (which is utter BS), after three different calls to find a solution, I was left high and dry with a lemon barrel. After I noticed that early dump, I documented then losing ~15fps per hundred rounds from 800-1100, then ~35fps per hundred from 1100-1400 rounds for the same powder lot, same bullet lot, same primer lot, same brass. Absolute train wreck. I was throwing almost a grain and a half more powder by the end to hit the same speed.

    I’ve had much smaller issues with other barrels, which makers investigated and replaced.

    Dang varmint, even my 260AI running super hot didn’t bleed speed that fast.

    I’d be willing to bet the problem is that 4-5 years ago there were some steel shortages (before the tariff issues) that caused most of the barrel makers to temporarily shift their steel suppliers. Some of them got stuck with steel that just didn’t come close to their normal spec. Just a rumor but I’d heard rock creek got hit particularly hard and had quite a run of junk barrels. Just a rumor though.

    Hmm, that's an interesting development, the only negative things I'd heard about PVA so far was that they seem to often blow their projected timelines by significant margins.

    I'm looking for a prefit shouldered or potentially barrel nut barrels, what barrel shops baby you had good luck with, or would recommend?

    My original plan was to get barrel nut Shilen from Northland Shooters Supply, but I kind of liked the shouldered prefit idea.

    I assumed something of the same vein, and frankly, I’m not blaming Rock Creek for turning out a lemon barrel, not in the least, even if it had been bad work on their part. Bad luck occasionally happens to all makers.

    But they COULD HAVE stood behind their product. But instead, they shrugged their shoulders and told me I was SOL, and counterintuitively substantiated what I was seeing couldn’t be happening because they believe 6 creed barrels should 3,000 to 4,000 rounds without losing speed - even confirming H4350 and 105 Hybrids lasting that long, assured BS - which should have been even MORE reason to have my barrel/rifle into their shop to figure out why it was bleeding speed so fast. Hell, even blame the throating job or SOMETHING... So I didn’t feel well served by, “that’s super weird, it should last 3-4,000 rounds, we don’t know why that could be happening, but thanks for buying our barrel, call us when you want another...” Nah bro...

    Proof Research, or a Bartlein prefit from Altus. Either of these will be exceptional.

    My Bartlein barrel smithed by Stuteville Precision that came with my Impact rifle, and the Bartlein prefit I got from Altus both shoot extremely well. The first is starting to get a wee bit long in the tooth. The Stuteville chamber looked much nicer new than the Altus barrel did new, but it doesn't seem to affect accuracy.

    My buddy Jeff's Proof prefit he got somewhere shot very well for me one day he was playing with loads at the range and asked me to shoot a group with it. He whooped me with it the last match.

    I've heard nothing but good things about the Proof SS pre-fits, if I could get one in 6mm GT it would be a done deal. As good a deal as they are, it might even make sense to get a Dasher off the shelf and have a smith ream it to GT.

    Do you happen to be or know a Mil/LEO? Proof takes care of folks who take care of folks.

    Well given that you can get cut rifled Proof prefits for $509, most other well regarded shops offering similar quality prefits seem to run between $130 and $350 more. Savage style barrel nut prefits are less, the NSS Shilen prefit I was thinking about is ~$410 but.... well Salvage barrel nuts are pretty ug... Focused on the important stuff over here.

    Maybe I should just go with the Dasher, I just feel like I've read enough about Dashers being fumbly feeding that I'm a bit gun-shy. I saw Dasher specific MDT mags at my lgs the other day, maybe that would help.

    I don't intend to mess with forming, hydro forming, etc but I think at least Alpha makes Dasher brass now, maybe Peterson too, whether I can find any currently might be a question.

    I was originally going to get a KRG Bravo, but after reading for a while a lot of folks seem to prefer the MDT XRS in the same general price range, so I think I'll go that direction. I've seen a labor day sale already that will knock 10% off the chassis, so that's nice.

    My Dasher feeds great with both AICS mags with Primal Rights kits and MDT 6 Dasher mags. No issues in the Impact or the Axiom actions. Never say never, but I have never had a mis-feed.

    I have 1 Primal Rights/AICS mag that feeds like 99% without issues, occasionally (1 per match it seems) it will nosedive a round a bit. I can feel it immediately in the bolt and have to reach into the action and press the rim of the round down to get it to feed.
    I have 1 Primal Rights/AICS mag that is more like 70% and it's marked with an X so I know which is which
    I have 2 MDT 12 Rounders that are thus far problem free but I only have ~200 rounds between them to verify.

    BR blocked 12rnd MDT’s and HRD Gear blocks for AW mags. No hiccups, Defiance action, Manners Gen2 chassis.

    Pretty hard to short stroke a blocked mag - a lot more of us short stroke and choke full length short action cartridges like 6 creed than do Dashers or BRA’s. Reported “poor feeding” is far more often shooter error of short stroking the bolt - blocking mags and moving the rounds forward almost wholly prevents that opportunity.

    1200 yards ;)


    Good tip.

    I do a lot more holding than dialing, until I get to 10 mils, and then I will dial some elevation to keep me closer to the middle of the glass. Since I hold so much, I have to make a conscious decision to go dial back.

    Some optic turrets are more forgiving than others in preventing the dreaded dev off

    but I don’t dial back to zero right away. My pre-stage check, when the RO says “is the shooter ready?” Includes glancing at the turret to make sure it reads zero.

    coming off the stage I sometimes need to think about what my dope originally said and what I wound up getting hits with so I’ll want to go back and reference current setting on turret. But I usually do get it set back to zero well before coming to the line on the next stage
